From Middle English curious (“careful, meticulous; ingenious, skilful; expert, learned; concerned about (something); eager; curious, inquisitive; prying; carefully or skilfully made; exquisite, fine; sophisticated; recondite; magic or occult; absorbing, painstaking”) [and other forms], from Old French curios, curius (modern French curieux (“curious, inquisitive; interesting, quaint, unusual”)), and its etymon Latin c?ri?sus (“careful; complicated, elaborate; careworn; curious, inquisitive; meddlesome, prying”), from c?ra (“care, concern; anxiety; sorrow; attention; administration, management; command, office; guardianship”) (from Proto-Indo-European *k?eys- (“to heed”)) + -?sus (suffix meaning ‘full of, prone to’ forming adjectives from nouns). The English word is cognate with Italian curioso (“curious, inquisitive”), Occitan curios, Portuguese curioso (“curious, inquisitive; odd, out of the ordinary”), Spanish curioso (“curious, inquisitive; interesting; odd, strange; quaint”).
